Re: Bullet dilema for long range deer hunting.
JWP475 advice is spot on with the TSX. I have only shot them to 200yds at deer, but they are awesome penetrators, and in my experience, mushroom great at all velocities. I used to push the 100gn TSX in my .25-06 Sendero to 3200fps (+) and I recovered one the whole time I used them.
The bullet that I recovered was from a whitetail that I shot as he was making a hasty retreat back to the woods. When his rear-end filled the Leupold, I touched off a round which resulted in an abrupt halt on his part.
I recovered the TSX under the hide in his chest/shoulder area. The bullet weighed 99.805gn and was a picture perfect muchroom, just like Barnes advertises. I've done that same shot with 150gn Ballistic Tips in the 7mmRM at less distance that didn't even begin to penetrate like that!
I'm not sure how them perform at longer ranges (400yds +), but I would not be afraid to use them on anything in North America at distances less than this. I would imagine the Tipped version is just as awesome. The GMX from Hornady may provide the same performance, not sure as I haven't used them. JohnnyK.
